Denial is refusing to believe or even perceive painful realities. For example, the dentist is telling the girl that she has a cavity but she insists that she doesn't because she claims to brush her teeth everyday.
Writing poetry is helping me feel better after that awful breakup!
Reaction Formation is switching unacceptable impulses into their opposites. For example, the girl has a fear of clowns , but says she loves them when her friend asks if she wants to take a picture with it.
You're mad that I forgot the sunscreen, aren't you?
Displacement is shifting sexual or aggressive impulses toward a more acceptable or less threatening object or person. For example, the waitress takes out the anger of her friend canceling on her on her customer.
Sublimation is the transferring of unacceptable impulses into socially valued motives. For example, the girl is dealing with the breakup by writing down her feelings in poetry.
Projection is disguising one's own threatening impulses by attributing them to others. For example, the girl is mad because she forgot sunscreen but is assuming that her friend is mad instead of her.
Regression is retreating to a more infantile psychosexual stage, where some psychic energy remains fixated. For example, the girl is stressed out about an assignment due tomorrow, so to cope with the stress she was comforted with the blanket from her childhood.
I have no time to get this paper in by tomorrow! Luckily, I have my baby blanket to help with the stress!
